Higgcision Updates 2014

Abstract

During the 2014 Summer Conferences, both ATLAS and CMS Collaborations of the LHC experiments have demonstrated tremendous efforts in treatment of data and processing more data such that most data on signal strengths have improved; especially the diphoton and fermionic modes of both experiments. Here in this note we perform an update to our previous model-independent Higgs precision analysis -- Higgcision. We found the followings: (i) the uncertainties on most couplings shrink about 10--20%, (ii) the nonstandard (e.g. invisible) decay branching ratio of the Higgs boson is constrained to be less than 19% if only the width is allowed to vary, (iii) the gauge-Higgs coupling C_v is constrained to be 0.94 +0.11 -0.12, in which the uncertainty is reduced by about 10%, and (iv) the standard model (SM) Higgs boson still provides the best fit to all the Higgs boson data, and compared to the previous results the SM Higgs boson now enjoys a higher p value than the last year.

21 pages, containing 5 figures and 9 tables. Updates in tables and figures due to the most recent published ATLAS diphoton rate in arXiv:1408.7084 [hep-ex]. The SM enjoys a very good p value
